Patented Dec. 1, 1931 UNITED STATES EMILE WEIL, OF NEW ORLEANS, LOUISIANA i MASONRY WALL AND DAMPPROOF INSERT THEREFOR Application filed September a, 1930. Serial no. 483,864.

The invention relates to improvements in masonry and like .walls and a waterproof protective insert for use in the mortar or plastic joints thereof. The invention aims to provide an insert which may be applied in any desired length and/or height or in overlapping or abutting lengths to cover any desired number of bricks or blocks and prevent penetration of water or dampness through the joints of the wall.

The invention further aims to provide an insert which may be readily applied in either vertical or horizontal joints, which will conform and adjust itself to irregularities in the contact faces of the bricks or blocks of which the wall is composed, and which will interlock with the mortar or other binder and will not interfere with bonding surface efficiency of the mortar or other binder.

The invention further aims to provide an insert having a plurality of flexible, yielding contact points projecting from the mortar or other binder throughout the extent of the joint for ready spreading in sealing contact with the bricks or blocks of which the wall is composed.

The invention further aims to provide an insert having plural contact with each brick or block which it engages, such contact continuing throughout the extent of the joint and lengthwise of the insert.

Other objects will appear hereinafter, in the description of the invention which includes v the construction, arrangement and combination of parts, and in the claims in which the invention is particularly defined.

In the drawings, r i Figure 1 is an elevation showing the face of a wall and shows in X-ray fashionthe waterproofing insert strip laidboth horizontally and vertically and simply assumes that one looks straight through the mortar and sees the strips of the insert in the joints.

Figure 2 is a top plan view of a portion of a wallot one brick thickness and shows the waterproofing insert strip running horizon- I tally from a to a on top of thebricks, while it also shows the waterproofing insert strip used vertically runningdown through the joints at the points b, b, b and b. The

vertical strip is shown overlapping either on one side or the other of the horizontal strip 5 and b, is shown on both sides of the horizontal strip at b and is shownin X-ray fashion at 6', simply assuming that one looks straight down through the horizontal strip and sees the vertical strip, abutting and interlocking with the horizontal stripas fur ther explained in Figure 6.

Figures 8, 4, 5 and 6 are sectlons on lines 33, Jr-4e, 55 and 6-6 of Figure 2. Atthe points a is seen a sectional view of the waterproofing insert strips, of the upperone of which is seen a top horizontal'view in Figure 2 from a to a. At the point I) is seen a side view of the waterproofing insert strip, the top of which is seen at the point I) in Figure 2. At the points I) is seen .a side view of the waterproofing insert strips, the top of which is seen at the points 6 in Figure 2. At the point I) is seen a side view of the waterproofing insert strip, the top of which is seen at the point 6" in Figure 2. At the point 6 is seen a side view of the waterproofing insert strip, thetop of which is seen in X- ray fashion at the point 6 in Figure 2.

Figures 7, 8, 9 and 10 are sectional views of various shapes of the waterproofing insert strip of my invention adapted to lie in the joints; but the waterproofinginsert strip may be of any shape which willprovide'a plurality, of 'contact points projecting from the mortar or other binder throughout the extent of the joint for ready spreading in sealing contact with the bricks or blocks of which the wall is composed.

' Figure 11 is a sectionalview of the'same shape of the waterproofing insert strip ofmy invention shown in Figure 10, but in Figure 11 the waterproofinginsert strip is shown lying in a horizontal joint embedded in the mortar as it would appear withoutcontact with the upper brick or block of the wall.-

Figure 12 is a compressed'view of Figure 11 showing how the waterproofing insert strip would spread and make contact when the upper brick or block is placed in position and a brick or block has made contact with the opposite sides of the waterproofing insert strip in the finished wall.

"binder, and that in Figure 12 a brick or block been applied along both of the lines 8, representing the upper and lower surfaces of the binder.

Referring to the drawings, in Figures 1, 2, 3, 4, 5 and 6, vertically disposed portions of the waterproofing insert strip are indicated at b, 5, Z) and 6', while horizontally disposed portions of the waterproofing insert strip are indicated at a. The inserts are embedded in the mortar joints, as shown 1n Figures 11 and 12, with flexible, yielding, protruding portions, points orribs, 0 forming a plural contact with the bricks or blocks 1 of the wall, which compress the protruding portions, points or ribs and effect a Water tightcontact. I

This waterproofing insert strip may be made in theform of .a continuous strip of any of the cross-sectional shapes shown in Figures 7, 8, :9 and L0 or any other shape which would provide two or more contact portions, points or ri bs. I

The waterproofing insert strip may be of any material, but preferably of asphaltic, bituminous or :coaltar mastic material, compound or composition, or any other waterproof .material compound, .or composition, which will not be deformed by ordinary handling in hot weather or become hard and brittle incold weathenand which will provide flexible, yielding, protruding contact portions, points or ribs 0 to provide a superior Contact and an absolutely effective water seal; and may have a reinforcement (Z, preferably of waterproofing paper, but of any paper, felt, or metal, for better maintaining J the section of the waterproofing insert strip in its handling and installation. These re mforcements (Z will serve only to stiffen the body of the waterproofing strip and will not interfere with 'or stiffen the flexible, yielding contact portions, points or ribs 0, since these reinforcements are disposed within the grooves or recesses between the projecting portlons, ribs or points. Reinforcement means, in the form of .a .rod or strip of metal m may be inserted substantially centrally the body ofthe waterproofing insert strip ex tending longitudinally thereof as shownin Figures 7,8,9, 10, 11 and 12. 7

The waterproofing strip as .an insert for joints of masonry may be either vertical or horizontal or both for the purpose of preventing penetration of moisture or water through the oints by virtue of its sealed contact points in compressed engagement with the masonry members. I i

The waterproofing insert strip may be of any length for simplification of manufacture or installation and of any size for any thickness of joint.

These strips or inserts are so formed to provide automatically in any method of in stalling in either or both vertical or horizontal joints a plural contact with the masonry members of the wall. In cross-section these strips are preferably in the general form of a cross providing projections approximately 90" apart so that two projections are readily available for contact with the'bri'cks or blocks on either side, and no particular care is required in placing the strips so that two projections are exposed on each side of the mortar or other binder; In any event the waterproofing insert strip is of a section providing plural projections on each face of the mortar.

It will be noted that the inserts are slightly larger the joint thickness to assure contact and cover any irregularities in the masonry or contact members of the wall. 7

These waterproofing insert strips may be used for caulking openings -in walls, be

ing placed between the metal, wood or other frames and the contact wall for the prevention of water penetration .at such points, as is now prevalent; and they may also be used for for the prevention of water penetration at such points, as is now prevalent. 1

It will be seen that in Figures '3, 4:, and 5 the waterproofing insert strip used vertically merely overlaps on one side or the other the waterproofinginsert strip used horizontally or overlaps on both sides of it; but in Figure 6 is shown a preferred form of the waterproofing insert strip used vertically in which the vertical waterproofing insert strip has keyed or tapered ends, f. V g Thesekeyed or tapered ends, tho shown in Figure 6 to be pyramidical in shape, may be of any desired or convenient shape, adapted to extend at right angles thereto into the longitudinal recesses or grooves of the horizonstantially continuous throughout both ho'ri- V zontaland vertical'joints of themasonry wall. i

The invention may be applied to a of one brick or block thickness or it maybe applied to a wall of greater thickness comprising a plurality of courses, with'equal facility and with equal effectiveness.

Referring to Figure 12 showing the four;

pointed star shape of the waterproofing insert strip with the sharpened ends depressed," this view shows the manner in which the abutting faces of the masonry or other construction depress and force the projections 3 into the mortar or binder. The mortar or binder yields to some extent as indicated by the position in Figure 12 of the projectlons of the waterproofing insert strip while providing sufficient resistance that the depressed flexible, yielding projections are maintained in effective sealing engagement with the irregularities of the abutting faces of the masonry.

A space is provided at point 0, Figures 7, 8, 9, 10, 11 and 12, beyond the edge of the reinforcement d, which will permit expansion and flow of the mastic material inwardly against the abutting bricks or blocks for'further sealing effect after the compression of the waterproofing insert strip by the abutting bricks or blocks, outward flow being prevented by the mortar or other binder.

The space 0 also provides for flow in the event of expansion of the mastic material due to temperature changes after the masonry wall is set, and to more firmly seal the joint.
